You have a proper understanding of voice communications (SIP call flows, WebRTC, SIP over WebSockets, and so on)

You have more than 6 years mobile app development experience.

You have experience implementing WebRTC with Flutter.

You are comfortable with the GetX package for routing and state management.

You are able to write platform-specific code (Kotlin and Swift) if necessary.

You are have experience implementing Callkeep (CallKit and Android Connection Service)

You speak English fluently.

Implement the missing features outlined below.

MISSING FEATURES

Receive incoming calls when the app is not active

Accept / Reject incoming calls with system user interface, like a typical SIM call.

Active call control feature - Activate dial pad and transfer to teammate

View call information on the active call screen. Call information such as number called, and duration of an active call.

Receive push notifications for missed calls while offline

App call logs should appear on system call logs. That is; dialled, received and missed calls from app, should appear on your standard phone logs.
